Vulnerability from github – Published: 2026-07-07 21:31 – Updated: 2026-07-07 21:31

Details

HTTP::Tiny versions before 0.095 for Perl forward credential headers to cross-origin redirect targets.

When the server returns a 3xx redirect, _maybe_redirect follows the Location: header and _prepare_headers_and_cb re-merges the caller's headers argument into the new request, without checking whether the redirect target shares an origin with the original URL. Caller-supplied Authorization, Cookie and Proxy-Authorization headers are therefore re-sent to whatever host the redirect names, across scheme, host or port boundaries, and including https to http downgrades that expose them in plaintext on the wire.

The HTTP::Tiny POD note that "Authorization headers will not be included in a redirected request" applied only to the URL-userinfo Basic-auth path, not to headers passed explicitly by the caller.

Severity

7.1 (High)

Summary

HTTP::Tiny versions before 0.095 for Perl forward credential headers to cross-origin redirect targets. When the server returns a 3xx redirect, `_maybe_redirect` follows the `Location:` header and `_prepare_headers_and_cb` re-merges the caller's `headers` argument into the new request, without checking whether the redirect target shares an origin with the original URL. Caller-supplied `Authorization`, `Cookie` and `Proxy-Authorization` headers are therefore re-sent to whatever host the redirect names, across scheme, host or port boundaries, and including `https` to `http` downgrades that expose them in plaintext on the wire. The HTTP::Tiny POD note that "Authorization headers will not be included in a redirected request" applied only to the URL-userinfo Basic-auth path, not to headers passed explicitly by the caller.
